To all whom it may concern:

Be it known that 1, PETER A. MCGURRIN, a subject of the King of Great Britain, and resident of-Norwood, county of Hamilton, State of Ohio, have invented certain new and A, of the case and is engaged by the nut, 12.

The extension, (1", is engaged likewise by a packing nut, e. llousmg, F, carrying a tram of gears for registering the revo- I lutions of the shaft, B, is seated upon the mounting the wheel in its case so as to pre- 1 vent leakage therefrom, while not disturbing the sensitiveness' of the instrument. object is attained by the means described in the specification and illustrated in the accompanying drawings, in which,

form of a shallow cylinder, A, having adjacent to one side an admission'po'rt, a, and

in 'alinenlent therewith an exit 'port, a. Admission port, a, has a screen, of. i In the walls of the cylinder there are three grooves, a, a, and a. The'wheel consists of ahub, l), radiating paddles or wings, I) and a disk, 11 which is located at one end of the paddles and is preferably formed integral therewith. The wheel is of a diameter nearly e ual to the internal diameter of the case lhe wheel is mounted in a metallic frame which consists of two spiders, 1), D-- whose arms are held together by posts, (I, d and The hubs of the spiders are perforated to pass the shaft, B to which the wheel 'is secured,

Surrounding the perfo ationsin the spiders annular recesses are met nular collars, b and b Collar, 12, projects from the underside of the huh, I), and collar, 1), projects from the top of disk, 11 into the seats formed in the spiders. In inserting the frame carrying the wheel into the case, the arms of the spiders and the posts, (I, d, and (F, are seated in the grooveaa, e and a, with the disk, I), uppermost. The spider, D, has an external and short cylindrical extension, d, which projects through the top,

The revolutions of the shaft g, are registered upon adding wheels, G which are mounted upon a shaft, y, to which the revolutions of shaft, y, are conveyed by means of a worm, The numbers on the wheel, G, are read through a slot, f, in the of the case, F.

to In operation the water passing through the Referring to the parts: thecase is in the casing, A, by pressing upward against the disk, holds the shoulder, b, in its seat with a pressure which is sullicient to prevent leakage between the shoulder and its seat.

The tendency for the water to leak out increases with the increase of pressure in the case. The difl'icultyalso of rotating the wheel increases with the pressure with which i The creases with its ressure. T hercfore, where the pressure 111 t 10 case, A, [S small, the ease with which the Wheel will move is greater because of the shoulder if, being held with less pressure in its seat, and where the pressure in the case is thus lessenhd there is a lessened tendency of the water toescape around the shoulder, 6 By -applicants arrangement, therefore, the' meter automatically adjusts itself to the demands made upon it.

' What I clai-nris:

1. In a water meter the combination of a casing having a water channel therethrough and having a perforation in its top, a wheel in the casing andhaving adjacent to the top of the casing a disk, a shaft for the wheel proan annular shoulder upon the disk surroun ing the shaft and adapted to contact with the jectijng through the perforation in the casm top of the casingeround the perforation, and

radiating paddles projecting down from the disk, whereby the pressure of the water against the disk holds the shoulder against the to of the casing.

2. n a water meter the combination of a eylindriealease having groaves in its wells, 'a

"frame consisting of spiders connected ,by posts, a Wheel j'ournaled between the spiders,\- I

the spiders being seated in the ease with the posts projecting into the grooves, the pe- I riphery of the tvheel being adjacent to the j walls of the case, a means of securing the upper spider against the top of the case, a shaft projecting through the spiders and the top of 15 [the case, a train of registering gears mounted upon the top of the case, and means of j (-euplingthe train to the shaft.
